| 摘 要： | 从水电开发中的生态环境保护问题出发，对河流系统生态环境需水量的概念及其内涵进行了探讨。以云南苏帕河流域为例，认为河流生态环境需水量为基本生态环境需水量、输沙需水量和污染防治需水量的有机整合。苏帕河流域朝阳、乌泥河、阿鸠田河的河流生态环境需水量分别为1.54×10^8m^3、3.31×10^8m^3、3.56×10^8m^3，分别占来水量的48.9％、44.9％和52.3％，其中输沙需水量均占99％以上。因此，保护苏帕河流域生态环境的关键是在水电开发中防治水土流失，降低输沙需水量。

| Abstract: | The concept and the intension of water demand for ecological environment of river system were discussed from a point of view of the protection of ecological environment during hydroelectric development. Taking Supa River basin in Yunnan Province as an example, it is determined that the water demand for river ecological environment is the conformity of the basic eco-environment water requirement, water demands for sediment transport and for pollution prevention. And the water demands for ecological environment in Chaoyang River, Wuni River and Ajiutian River on Supa River basin are 1.54×10^8m^3、3.31×10^8m^3、3.56×10^8m^3 separately, and the water demands for sediment transport are all over 99%, which are respectively 48.9%, 44.9% and 52.3% of the runoff. So during the process of hydroelectric development, the key of protecting the environment of Supa River basin is to control soil erosion and decrease the water demand for sediment transport. |
